Xenoblade Chronicles Definition Edition is an edition of an existing work, fitting your top definition.
But to be more precise, a remaster isn't just an edit: patches, mods, and ports are also edits. A Remaster is an edition fit for newer generations of hardware. They generally replace outdated engines and graphics with ones appropriate for the generation.
Don't unsimplify my simplification.
In the old music and film days, even a "patch" would be considered a remaster.
